Rosetta’s Stone

Among the earliest forms of writing, Egyptian hieroglyphs were known long before they were deciphered. Despite the famed insanity of Napoleon, his visit to Egypt led to the discovery of the Rosetta Stone and we’ve been able to read what was once pure mystery for over a century now. A week ago today, Rosetta, a robotic space probe, landed on a comet in flight. For a guy who finds a rendezvous with a bus that runs on a supposedly regular schedule a challenge, this is nothing but mind-blowing. If you know the math, you’ll go far. Comets, you see, have long been the provenance of both religion and science. The ancients, apart from being very religious, we also first rate astronomers. Limited by a universe that circled the earth, they nevertheless figured out how to predict things like solstices and eclipses and phases of the moon. Some suggest that megalithic structures as impressive as Stonehenge and the pyramids of Giza were aligned to significant celestial events. The eyes in the skies.

Comets were generally considered harbingers. Even in ancient times they were difficult to figure out; their orbits aren’t easily deciphered and some never survive their close encounter with Old Sol. Still, they can be impressive. Living in the cloudier climes, glimpsing comets is not a guarantee. Light pollution, especially on the horizon, interferes with all kinds of observations. Now, however, the European Space Agency has shown us that it can be done without seeing where you’re going. A decade of travel time, after at least as long of planning for the trip, and you can boldly go where no person has gone before. Recordings of the electromagnetic frequencies, translated into human audible range, confirm everything from Predator to Signs. 67P/Churyumov–Gerasimenko has its day in the sun and 2001 every day comes closer.

Just a year ago comet ISON disappointed many in its failure to live up to the hype. In our workaday world, we’re eager for a harbinger of some kind. A sign that something out there can still evoke wonder. Comets have long been stripped of their religious garb. They are merely rocks and ice lit up by the sun on their weary trek through the cold loneliness of space. Still, landing on a comet can’t help but change our perspective. It’s like looking at the earth from the moon. Or Mars. We name our planets after gods, but comets bear the names of human discoverers. And we have constructed our own Rosetta stone to read the mysteries of the universe. Meanwhile, the bus waits for no one. If you calculate the trajectory correctly, you’ll hopefully get to work on time. And that, after all, is what really matters.


I See Only Nothing

Once considered to be bad omens, comets are becoming a fad for those who can take their eyes off the screen for a few moments to look at the sky. Comet ISON (C/2012 S1), apart from falling trippingly from the tongue, is apparently now visible with the naked eye. I’ve been looking forward to this comet since at least January, although living just to the west of New York City complicates viewing possibilities quite a bit. You see, although I am now an urbanite, I’m really a rural rube at heart. I grew up in a town of less than 1000, and was born in a town of less than 15000. I attended college in a small town and my first teaching job was in a rural setting in Wisconsin. Apart from the fact that I’m now convinced people have very little control over their own destinies, I have preferred to live in places where I can see the night-time sky. Perhaps it was my love of science fiction as a child, but for whatever reason, space has always captured my imagination. I used to drag my brother out on frigid nights to look at the stars, and even tried to teach myself the azimuth coordinate system to document precisely where I’d seen something. I took astronomy classes in high school and in college. In middle school I did an intensive report on comets that saved my science grade that year.

Comet ISON, however, has been refusing to behave as it was projected that it might. Although it could still turn into a very bright sky-show, so far it has been difficult to spot, and, at least for my location, at inconvenient hours of the day. Much to the chagrin of creationists, ISON is 4.6 billion years old, although it is just getting out for it’s first tour of the solar system. Part of the Oort cloud region, Comet ISON is probably a piece of a never-formed planet out past Neptune that decided to take its first cosmic stroll about a million years ago. It’s had a date with the sun since that time. The scientific jury’s still out as to whether ISON will go out with a blaze of glory after its close encounter with our sun and if it will come back around again to wow generations of our distant progeny (presuming we survive that long). For me it will be a matter of seeing if the clouds ever break in the east at 4 a.m. so that I can actually get a glimpse of the sky.

Comets were once thought to be heralds of the gods. Like other variable objects in an otherwise pretty predictable night-time sky, they can be either very bright or very dim (even invisible, for all practical purposes). When Halley’s Comet came around in 1986 I was living in Boston and couldn’t see the heavenly visitor. In 1996 Hyakutake buzzed earth, I stood in wonder in the woods of Wisconsin, photographing my first comet. A year later when Hale-Bopp blazed through the sky, I was out with my camera trying to capture it on film (a medium, I understand, that is about as old as Comet ISON). Were these visitors bad omens? One comet may have been decidedly devastating for our dinosaur friends, while some speculate that life on earth was seeded by a comet (making it a kind of secular god, I suppose). I’m only convinced that we have no control over our fate as I stand outside at 4 a.m. yet again, only to find clouds in the east and a comet in my heart.
